(a)[5]
Assuming that the forces are in equilibrium, determine the values of $F$ and $G$.
(b)[2]
If $F = 3$ instead, determine the value of $G$ for which the resultant of the forces is perpendicular to the $10\,\text{N}$ force.

Forces and equilibrium — practice question
Four forces acting at one point lie in the same plane. Their magnitudes are $10\,\text{N}$, $F\,\text{N}$, $G\,\text{N}$ and $2F\,\text{N}$. The directions of the forces are shown in the diagram.
